Product Description
The Allen-Bradley PowerFlex 700 series 20BC085A0NNNAEC0 is a compact, 45 kW, 400V AC, 85A variable frequency AC drive designed for industrial AC motor control using a 3-phase power source. Featuring an Ethernet/IP module for communication, a CM choke, and a CE filter for EMC compliance, this panel-mountable, non-waterproof Frame 4 drive (also known as a zero-stacking drive) lacks a human-machine interface and braking device. It supports line transients up to 6000V (IEEE C62.41-1991), showering arc transients of up to 1500V, and has a short circuit rating of 200,000A, with a motor power ratio between 1:2 and 2:1. It uses 24V DC for I/O voltage and can operate at altitudes up to 1000 meters without derating.
Is Your Device Showing These Signs?
The Allen Bradley 20BC085A0NNNAEC0 Servo Drive commonly experiences issues related to IGBT failures, often indicated by fault codes on the HMI. Resolving this requires replacing the damaged IGBT module and thoroughly testing gate drive circuitry. Capacitor degradation within the DC bus is another frequent problem, leading to voltage fluctuations and drive instability; replacement of the DC bus capacitors is necessary. Encoder feedback issues, stemming from faulty encoder cables or resolver malfunction, cause erratic motor behavior; inspect and replace the encoder cable or resolver as needed. Overcurrent faults are addressed by examining the motor windings for shorts or grounds, and by verifying proper current sensor calibration within the drive.

Our Repair Process for the
20BC085A0NNNAEC0
Our repair process for the Allen Bradley 20BC085A0NNNAEC0 Servo Drive begins with diagnosing the fault codes displayed on the HMI, particularly those indicating IGBT failures, which necessitates immediate replacement of the damaged IGBT module and rigorous testing of the gate drive circuitry. We then address capacitor degradation within the DC bus by replacing the DC bus capacitors to eliminate voltage fluctuations and ensure drive stability. Encoder feedback issues are resolved through a thorough inspection and replacement of the encoder cable or resolver to correct erratic motor behavior. Finally, overcurrent faults are mitigated by examining the motor windings for shorts or grounds and verifying the proper calibration of the current sensors within the drive.
